Official Creality 42-34 Stepper Motor with Pressed on Fitting - 3D
The BJ42D15-26V10 typically features a 4-wire bipolar configuration. Understanding the wire pairings is critical to prevent damage to your stepper driver. Phase A: Black (A+) and Green (A-) Phase B: Red (B+) and Blue (B-)
The is a high-performance, compact stepper motor frequently used in precision automation, 3D printing (notably in Creality Ender series printers), and small CNC machinery . Manufactured by Keli Motor Group, this 2-phase NEMA 17 stepper motor is recognized for its reliability, smooth operation, and optimized torque-to-size ratio.
Note: Wire color configurations can vary by factory supplier. Always verify winding pairs using a multimeter before powering your driver. Identifying the Pairs with a Multimeter bj42d15 26v10 stepper motor datasheet
When designing circuits or selecting motor drivers, the electrical and mechanical limits of the motor dictate system stability. Below are the definitive specifications for the BJ42D15-26V10. Electrical Specifications 2.6 Volts DC Rated Current: 1.0 Ampere per phase Phase Resistance: 2.6 Ohms ±plus or minus 10% (at 20°C) Phase Inductance: Approximately 4.0 mH to 5.0 mH ±plus or minus Insulation Class: Class B (up to 130°C) Mechanical Specifications
